我有一个滚动视图，其中有多个图像视图，我在其上应用平移手势来拖动图像视图并添加到另一个视图。问题是当我尝试滚动滚动视图时，首先识别平移手势并调用平移操作而不是滚动视图滚动。这是我的平移代码
-(void)move:(UIPanGestureRecognizer *)sender
{
[[baseView superview] bringSubviewToFront:baseView]; //sender.view];
[hatScroll setScrollEnabled:NO];
// We pass in the gesture to a method that will help us align our touches so that the pan and pinch will seems to originate between the fingers instead of other points or center point of the UIView
[self adjustAnchorPointForGestureRecognizer:sender];
if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateBegan) {
if ([[[sender view] superview] superview] == itemView || [[[sender view] superview] superview] == itemView_iphone5) // adds the imageview in the item scroll
{
int tag = [[sender view] tag] / 100;
UIScrollView *tempScroll;
if (window.bounds.size.height != 568)
tempScroll = (UIScrollView *)[itemView viewWithTag:-tag];
else
tempScroll = (UIScrollView *)[itemView_iphone5 viewWithTag:-tag];
CGRect frame = CGRectFromString([itemFrameDict objectForKey:[NSString stringWithFormat:@"%i",[[sender view] tag]]]);
CGAffineTransform transform = temp.transform;
UIImageView *tempImageView = [[UIImageView alloc] initWithImage: [(UIImageView *) [sender view] image]];
tempImageView.tag = [[sender view] tag];
tempImageView.frame = frame;
[tempImageView setTransform:transform];
[tempImageView setFrame:frame];
[tempImageView setUserInteractionEnabled:YES];
[tempScroll addSubview:tempImageView];
UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)];
panRecognizer.cancelsTouchesInView = NO;
panRecognizer.delaysTouchesBegan = NO;
panRecognizer.delaysTouchesEnded = NO;
[panRecognizer setDelegate:self];
[tempImageView addGestureRecognizer:panRecognizer];
}
}
if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateChanged)
{
CGPoint translatedPoint = [sender locationInView:[[sender view] superview]] ;
newTranslatedPoint = [[[sender view] superview] convertPoint:translatedPoint toView:baseView];
if (window.bounds.size.height != 568)
{
if ([sender view].frame.size.width == 35 && [sender view].frame.size.height == 35)
[[sender view] sizeToFit];
}
else
{
if ([sender view].frame.size.width == 45 && [sender view].frame.size.height == 45)
[[sender view] sizeToFit];
}
[sender view].center = CGPointMake(newTranslatedPoint.x, newTranslatedPoint.y);
[baseView addSubview:[sender view]];
}
if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateEnded)
{
[hatScroll setScrollEnabled:YES];
[self.view insertSubview:baseView atIndex:2];
CGPoint newPoint;
if (window.bounds.size.height != 568)
newPoint = [[[sender view] superview] convertPoint:newTranslatedPoint toView:itemView];
else
newPoint = [[[sender view] superview] convertPoint:newTranslatedPoint toView:itemView_iphone5];
if (newPoint.y < 0)
{
UIPinchGestureRecognizer *pinchRecognizer = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(scale:)];
[pinchRecognizer setDelegate:self];
[[sender view] addGestureRecognizer:pinchRecognizer];
UIRotationGestureRecognizer *rotationRecognizer = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotate:)];
[rotationRecognizer setDelegate:self];
[[sender view] addGestureRecognizer:rotationRecognizer];
}
else if (newPoint.y > 0)
{
int tag = [[sender view] tag] / 100;
UIScrollView *tempScroll;
if (window.bounds.size.height != 568)
tempScroll = (UIScrollView *)[itemView viewWithTag:-tag];
else
tempScroll = (UIScrollView *)[itemView_iphone5 viewWithTag:-tag];
CGRect frame = CGRectFromString([itemFrameDict objectForKey:[NSString stringWithFormat:@"%i",[[sender view] tag]]]);
CGAffineTransform transform = temp.transform;
[[sender view] setTransform:transform];
[[sender view] setFrame:frame];
[tempScroll addSubview:[sender view]];
}
}
}
有任何想法吗？我怎么能得到这个。随时在提到的代码中询问查询。
